• /list - retrieves all participants, requires whitelist

3. Keys, ABI and Web3 communication layer

• assumption: testnet servers
• keys on backend layer
• transaction fees on backend keys
• integrates Web3 as API

4. Vyper layer (VerifiedOpinion contract)

• whitelist -> premium users/integrators
• opinionList -> read for whitelisted addresses
• opinionMapping (phone_number -> []opinions) -> free access
